The primary differences lie in the solid content and the silicone oxygen bond content. The specific model can be selected based on performance requirements and cost considerations. The SH-305 serves as the base version, as the model number increases (e.g., SH-306, SH-308, SH-309), both the solid content and siloxane bond content are higher. For detailed specifications, please refer to the product detail pages.

SH-113 is a kind of siloxane polymer, applied to formulate high-temperature resistant coatings.

SH-109 is a kind of siloxane polymer, applied to formulate protective clear topcoat with excellent stain resistance, easy cleaning and anti-graffiti property.

SH-216 is a kind of epoxy siloxane hybrids resin, used for the formulation of heavy-duty corrosion resistance coatings with longlasting protection.

SH-217 is a kind of epoxy siloxane hybrids resin, applied to formulate Direct-to-Metal(DTM) coatings and conventional anti-corrosion protective coatings.

SH-3 series are belong to acrylic siloxane hybrids resin, applied to formulate conventional anti-corrosion protective coatings.

SH-20 Series: Amino-functional siloxane curing agents, for use with compatible resins.

Generally speaking, the coatings’ silicone oxygen bond formulated by SH-216 is much higher, which exhibits better weatherability, corrosion resistance. While SH-306 is a cost effective option, which could meet the most requirement of anti-corrosion protection. SH-216 will be the ideal choice if you purpose perfect performance and extremely long service life and could bear higher cost. However, we suggest SH-306 for conventional topcoat with competitive price.
