The main body of IOTA 9970 automotive crystal coating liquid is a special polysilazane, different from the common market coating products based mainly on siloxane. The product data state that after crystallization it forms a silica film layer, with high hardness, good transparency, oxidation resistance, UV resistance, high adhesion, good water beading, and a brightening effect on vehicle paint (especially outstanding on black cars). The product is described as having excellent durability.
Selection should not rely only on “high hardness,” “good water beading,” or “excellent durability.” First confirm the paint type and condition, pretreatment (washing, decontamination, degreasing, polishing, whether a primer is needed), application method and film thickness, curing/crystallization conditions, whether it is layered or covered with other coatings, and the project acceptance criteria for water beading, gloss/brightening, weathering, wash resistance, scratch resistance, and durability. This article does not equate product features with a specific service life, scratch-resistance grade, weathering duration, or salt-spray result. IOTA can provide polysilazane raw materials and corresponding product data; the company does not provide complete formulations or formulation development services.
Common requirements for automotive crystal coatings include water beading, brightening, easy cleaning, oxidation resistance, UV resistance, and durable protection. Different projects focus on different points: some on initial water beading and gloss, some on wash and weathering retention, some on black-car brightening and color depth, and some on application efficiency and reworkability. Selection should start with the paint type, target effect, and acceptance method, not just “crystal coating.”
| What to confirm | What to specify in an inquiry or sample request |
|---|---|
| Paint and pretreatment | OEM or refinish paint, color (especially black), paint condition; washing, decontamination, degreasing, polishing, primer, etc. |
| Application method | Hand application, spraying, or other method; ambient temperature and humidity, application area, target film thickness |
| Curing and crystallization | Curing/crystallization temperature, time, and humidity; whether heating is used, whether layers are applied, interval between layers |
| Companion system | Whether a primer, sealant, wax, or other coating is used; interlayer adhesion and compatibility |
| Acceptance criteria | Contact angle or water-beading performance, gloss/brightening, transparency, adhesion, wash resistance, weathering, scratch resistance, durability, etc. |
| Sample preparation | Sample size, paint type and color, number of applications, curing conditions, whether evaluated after aging or washing, sample quantity |
If the customer already has a test specification, obtain the original document first. When criteria are missing, confirm them with the project owner and test laboratory before making samples, so that both sides do not discover different interpretations of “pass” after testing.
The water beading, adhesion, and brightening performance of a crystal coating are closely related to paint pretreatment. Oil, old wax, polishing residue, or scratches on the paint surface can directly affect spreading, adhesion, and visual effect. Ambient temperature and humidity, application amount, wiping timing, and curing conditions also affect film uniformity and final appearance.
The product data state that after crystallization a silica film layer is formed. Actual application should confirm the curing/crystallization conditions. A tack-free or briefly set surface does not necessarily mean the final film performance has been reached. Whether to apply multiple layers, the interval between layers, and covering with other coatings should be confirmed with the specific system and customer process.
The product data state good water beading, good transparency, a brightening effect on vehicle paint, and especially outstanding performance on black cars. Water beading can be observed by contact angle or water-bead roll-off, but water beading is not the same as scratch resistance or weathering resistance. Brightening and black-car effects are affected by paint color, paint condition, applied film thickness, and lighting conditions, and should be evaluated by comparison with same-color actual vehicle samples, not judged only from wording or a single photo.
Transparency and adhesion should also be confirmed on the target paint and film thickness. For refinish paint, matte paint, or special coatings, compatibility and appearance changes should be confirmed first.
The product data state high hardness, oxidation resistance, UV resistance, high adhesion, and excellent durability. These features should be translated into specific test conditions: which test method and film thickness for hardness; which aging conditions for oxidation and UV resistance; and which evaluation—wash resistance, weathering, friction, or actual exposure—for durability. “Excellent durability” cannot be directly converted into a number of years, and “high hardness” cannot be directly equated with a scratch-resistance grade.
For vehicle paint protection, also confirm whether subsequent repair, polishing, or recoating is affected; such compatibility should be included in customer process validation.
Obtain the customer’s service conditions and acceptance criteria; confirm whether water beading, brightening, weathering, wash resistance, scratch resistance, and durability are targets or existing results.
Specify paint type and color, pretreatment, application method, ambient temperature and humidity, target film thickness, curing/crystallization conditions, and layering arrangement.
Check the current IOTA 9970 data, then have the user make representative samples and keep records of pretreatment, application, curing, and layering.
Arrange tests as agreed; keep sample identity, test conditions, observation photos, and evaluation results in the report. Before expanding use, confirm whether the samples represent actual vehicles and application conditions.
IOTA/Anhui Iota Silicone Oil Co., Ltd. positions itself as a solution provider across the organosilicon industry chain and can provide polysilazane raw materials and corresponding product data. When communicating, provide the paint type, existing application process, target effect, and curing equipment together to facilitate candidate screening; the company does not provide complete formulations or formulation development services.
That cannot be directly promised. Durability requires a defined evaluation method (wash resistance, weathering, friction, or actual exposure) and acceptance criteria, and corresponding test evidence. It cannot be converted into years from product features alone.
No. Water beading reflects surface wetting and water-shedding behavior. Scratch resistance must be evaluated separately by the corresponding test method and film thickness.
The product data state especially outstanding performance on black cars, but brightening is affected by paint color, paint condition, film thickness, lighting, and application. Confirm by comparison with same-color actual vehicle samples.
The data do not provide a specific curing/crystallization timetable. Confirm curing/crystallization conditions with the application environment, film thickness, and system. A tack-free or briefly set surface does not represent final performance.
It can be evaluated as a candidate approach, but first confirm interlayer adhesion, compatibility, and application intervals, and then evaluate the whole coating system.
Not necessarily. Hardness testing and scratch-resistance evaluation are different. Actual scratch resistance is also affected by film thickness, friction mode, contaminants, and cure degree.
