The quality of raw materials directly impacts formulation stability, coating performance, and brand reputation. However, the market today is flooded with resins and hardeners of unclear origin—many lacking COA or even diluted. If your business is using such products solely because of their low price, it’s time to reconsider. This article will help you understand why choosing an official Covestro distributor is a technical decision, not just a commercial one.
1. DISPERSION STABILITY AND PURITY
In paint and engineering plastic formulations, dispersion stability directly affects coverage, adhesion, and coating durability. Official Covestro products are strictly controlled for particle size, pH, moisture content, and purity in every production batch. With unverified products, fluctuations in particle size or incorrect HLB values can lead to poor dispersion, clumping, uneven color distribution, and inconsistent curing.
2. INCONSISTENT TECHNICAL SPECIFICATIONS LEAD TO FORMULATION DEVIATIONS
Certain technical parameters—such as NCO content, OH value, viscosity, and pot life—must remain stable for long-term formulation use. Unverified products are often diluted, leading to extended reaction times or reduced reactivity, disrupting the curing process. This not only compromises performance but can also damage surface quality and reduce resistance to moisture and UV exposure.
3. IMPACT ON ADHESION, WEATHER RESISTANCE AND CHEMICAL RESISTANCE
Industrial coatings and engineering plastics must adhere well to various substrates such as metal, plastic, and wood. If the hardener lacks sufficient reactivity or the resin is not system-compatible, the coating is prone to peeling. Non-genuine products may lack proper surface treatment or lose functional group activity, leading to reduced adhesion and chemical resistance. With Covestro, each product line features carefully engineered surface treatments and formulations tailored for specific applications.
4. LACK OF CONTROL OVER RAW MATERIAL QUALITY
The Certificate of Analysis (COA) allows technicians to verify that each raw material meets the required specifications. With unverified products lacking a reliable COA, formulation relies on guesswork, which is highly risky. COAs from official Covestro distributors include batch numbers, active content, viscosity, and key characteristic indices, enabling manufacturers to build a standardized quality control system and minimize input-related errors.
5. TECHNICAL SUPPORT IS A COMPETITIVE ADVANTAGE
When choosing an official distributor like Vichem, you receive support from product selection to mixing guidance and on-site troubleshooting. For example, if a coating shows cratering, technicians will evaluate the interaction between resin, hardener, and additives to resolve the issue. Unverified products can’t provide this level of support — and when problems arise, you risk both costly rework and damage to your brand reputation.

6. CONCLUSION
Unverified products may seem cheaper at first, but they can cause serious losses in formulation consistency, performance, and brand reputation. Choosing an official Covestro distributor like Vichem means choosing technical stability, direct support, and long-term product value. It’s a strategic decision for professional manufacturing businesses.
