                     High heating sol gel coating problem


I have a client who do high heating sol gel coating meet a problem.White ceramic coating on the tensile aluminum frying pan, when use machine to punch, the back of the rivet hole and in the middle of two rivet hole  cracked and fell off.

Problem picture

He need to make the coating non-yellowing (stain) at a reasonable temperature 280-350 degrees , punching hole and riveting without cracking off.

Methyl-trimethoxysilane has been used in the coating,according to the only picture from my client,we can solve from the adhesion.

We can add the additional silane dimethyl-dimethoxy- silane which can improve the resin toughness. Methyl- trimethoxysilane mixed directly with dimethyl-dimethoxy-silane, amount ratio can be determined empirically, such as by 4 to 1 .

If you have more advice to recommend other products or other method to provide high strengh and toughness,please share and thanks!

Applications:
3-Aminopropyltriethoxysilane applied in plastic products (including cables, glassfiber-reinforcement plastics etc.), rubber products, adhesives, coatings, pigments dispersion, inks, magnetic materials (plastic magnet and rubber magnet), metallic casting resins and resins concrete, etc.
3-Aminopropyltriethoxysilane maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate, and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.
It also improves adhesion between magnetic powder and organic resins and dispersion of magnetic powder inorganic resins. Also these magnetic appliances attain higher magnetic orientation and excellent magnetic properties, higher mechanical strength, good processability, excellent weathering resistance.
In glass-reinforced thermoset plastics, 3-Aminopropyltriethoxysilane enhances the flexural, compressive, and interlaminar shear strengths before and after exposure to humidity. It greatly improves wet electrical properties.
With nitrile, polysulfide, epoxy, urethane, and adhesives and sealants, it improves pigment dispersion and maximizes adhesion to glass, aluminum, and steel.
Glass-reinforced thermoplastics, polyamides, polyesters, and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure.
In glass fiber and mineral wool insulation, as a phenolics resin binder additive, It imparts moisture resistance and allows recovery after compression.
In shell molding foundry applications, 3-Aminopropyltriethoxysilane strengthens the bond between the phenolics binder and foundry sand.
In grinding wheels, 3-Aminopropyltriethoxysilane promotes an improved, water-resistant bond between the abrasive grit and phenolics resin binder.
Packing:
Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
