Automotive coating crystal liquid IOTA 9970 is based on a special polysilazane as the main product body, different from the coating products currently popular on the market that use siloxane as the main component; after crystallization, IOTA 9970 forms a silica film layer, featuring high hardness, good transparency, oxidation resistance, UV resistance, high adhesion, and good water repellency. It also has a brightening effect on car paint (especially outstanding on black cars), and the product offers excellent durability. When selecting it, first confirm the delivery form, application method, and crystallization/curing conditions, then evaluate film performance. Merely seeing the words "polysilazane coating crystal liquid" is not enough to decide whether it can be used in an existing shop or production line.
This article focuses on procurement and sampling for automotive paint coating: products all called coating crystal liquid differ in film-forming mechanism between special polysilazane systems and coating products based mainly on siloxane; the paint cleaning, degreasing, and polishing state before application, as well as the crystallization/curing conditions after application, both affect the final film performance. Before requesting a quote, clearly state the paint type, application method, and maintenance conditions; this reduces the risk of receiving samples that cannot be applied or that give inconsistent results.
Polysilazane coating crystal liquid, siloxane coating products, and silicone resin are different product categories. The coating products popular on the market mostly use siloxane as the main component; IOTA 9970 uses a special polysilazane as the main product body and forms a silica film layer after crystallization. Actual formulations still depend on chemical structure and reactive groups; products cannot be directly interchanged based on name alone.
The information you provided does not give solids content, solvent system, packaging specification, or dilution requirements. Before sampling, request the TDS and SDS from the supplier to confirm whether the base liquid is applied directly or needs dilution, the solvent type used, the applicable application viscosity, and the single-use amount.
| Delivery Form | Confirm Before Sampling | Conditions Easily Overlooked When Switching Materials |
|---|---|---|
| Base liquid applied directly | Solids content, viscosity, single coating amount, application tools | Application temperature and humidity; avoid cross-contamination |
| Diluted application system | Dilution solvent type, dilution ratio, mixing sequence | Storage stability after dilution, pot life |
| Companion pretreatment/maintenance system | Cleaning, degreasing, polishing state, companion maintenance agent | Pretreatment residue, maintenance time and car-wash restrictions |
This table is intended for organizing sampling documents and cannot serve as a formulation for equivalent substitution among different systems. When comparing price and single-use amount, normalize to a comparable active film-forming basis and check the test methods in each document.
The product introduction for IOTA 9970 lists the following features: high hardness, good transparency, oxidation resistance, UV resistance, high adhesion, good water repellency, a brightening effect on car paint (especially outstanding on black cars), and excellent durability. These data can be used to screen sampling directions but cannot directly serve as acceptance results for a customer's vehicle or finished film.
Application method and paint name only indicate the applicable direction. For actual application, the compatibility of the product with the paint type (especially black cars versus other colors), the pretreatment state, and companion maintenance agents must also be checked. If hardness, water repellency, and durability are required, these should be tested together with transparency, adhesion, and UV resistance, avoiding material selection based on a single "high hardness" or "good water repellency" marketing statement. The information you provided does not give hardness values, contact angle values, or weathering test conditions; before acceptance, the test methods and judgment criteria must be checked with the supplier.
The product introduction mentions that "after crystallization, a silica film layer is formed," which is a different judgment item from preliminary surface film formation after application. The information you provided does not give crystallization/curing time, temperature, humidity requirements, or maintenance-period restrictions; sampling should follow the supplier's TDS, and the application temperature and humidity, film thickness, and maintenance time should be recorded.
During sampling, record the actual paint state, pretreatment method, application amount, ambient temperature and humidity, and maintenance conditions. Do not directly transfer the curing or maintenance conditions of another coating crystal product to IOTA 9970. The brightening effect and durability should also be compared under the same paint, same application, and same maintenance conditions, avoiding judgment based on a single application's appearance.
| Working Conditions to Provide | What Must Be Clearly Stated | Corresponding Verification |
|---|---|---|
| Substrate and pretreatment | Paint type and color (black or other colors); cleaning, degreasing, polishing state | Adhesion, appearance, brightening effect |
| Application and amount | Wiping/buffing or other application methods; single-use amount; application temperature and humidity | Leveling, streaks, haze, water repellency |
| Crystallization/curing and maintenance | Crystallization/curing time and conditions (not given; follow TDS); maintenance period and car-wash restrictions | Film curing state and performance reproducibility |
| Service environment | Outdoor exposure, UV, car washing, acid rain or contaminant contact | UV resistance, oxidation resistance, durability, and water-repellency retention |
| Functional requirements | Whether it serves functions such as brightening, water repellency, UV resistance, oxidation resistance, hardening | Verify according to actual paint and maintenance conditions |
For statements such as high hardness, good transparency, oxidation resistance, UV resistance, high adhesion, good water repellency, brightening effect (especially outstanding on black cars), and durability in the product introduction, the test object, time, formulation, and judgment criteria must be checked before use. Test results for the base liquid, experimental film, and customer's full-vehicle film should be recorded separately.
First fix the paint type and color, pretreatment process, and existing application conditions, and list the acceptance items that must be met (adhesion, transparency, water repellency, brightening, UV resistance, durability, etc.).
Request the TDS and SDS of IOTA 9970 from the supplier, and check the delivery form, solids content, dilution requirements, crystallization/curing conditions, and maintenance restrictions; if information is insufficient, complete it first—do not presuppose application parameters.
Sample using the same paint and comparable amount, and keep records of formulation, batch, application, and maintenance; the brightening effect on black cars should be verified separately on black paint surfaces.
Check initial appearance, adhesion, and water repellency, then arrange UV resistance, oxidation resistance, or durability testing according to the application. Write the test conditions and pass thresholds into the sampling confirmation sheet.
What is the difference between IOTA 9970 and common coating products on the market?
The main product body is a special polysilazane, different from the coating products currently popular on the market that use siloxane as the main component; after crystallization, IOTA 9970 forms a silica film layer.
How long does crystallization/curing take?
The information you provided does not give crystallization/curing time and conditions; before sampling, request the TDS from the supplier and follow the maintenance period and car-wash restrictions specified in the TDS.
How high is the hardness?
The product introduction states "high hardness" but does not give specific values or test methods; before acceptance, check the hardness test conditions and judgment criteria with the supplier, and do not select materials based only on marketing statements.
Can the brightening effect on black cars be used directly as an acceptance indicator?
The product introduction mentions a brightening effect on car paint, especially outstanding on black cars; however, it should be verified under the same paint, same application, and same maintenance conditions, and results for the base liquid, experimental film, and full-vehicle film should be recorded separately.
How should water repellency and durability be verified?
Water repellency should be tested together with durability, UV resistance, oxidation resistance, adhesion, and transparency, and the application amount, ambient temperature and humidity, and maintenance conditions should be recorded; the data do not give contact angle values or weathering test conditions, so these must be checked with the supplier.
What information should be provided at minimum when requesting a quote?
Provide the paint type and color, pretreatment method, application method, target amount/film thickness, crystallization/curing and maintenance conditions, and service environment, and list acceptance items (adhesion, transparency, water repellency, brightening, UV resistance, durability, etc.). This information is more helpful for screening samples than asking only about a "hardness" or "water repellency" claim.
IOTA 9970 Automotive Coating Crystal Liquid: for preliminary verification of the special polysilazane main body, the silica film layer after crystallization, and application directions such as paint brightening, water repellency, and UV resistance. The specific formulation and application parameters depend on the paint, application method, and maintenance conditions.
