Wyncoat® reactive silicone additives are organic modified polydimethyl-siloxane terminated with carbinol. In a variety of polyurethane systems, hydroxylmethyl can be cross-linked with NCO, so that introduction of silicone into resin system can provide anti-graffiti and easy-cleaning properties.

2 ) Hydroxylalkyl type:
High purity polydimethylsiloxane with carbinol as the end group functional group. It can replace part of polyols to participate in the copolymerization reaction, so that the silicone component is introduced into the resin system, which provides a smooth feeling and anti graffiti properties for polyurethane coatings.
|Copolymerization with polyurethane resin to enhance softness and toughness
|Enhance the water repellency, flexibility, abrasion resistant and smoothness of resin
|Smooth, abrasion-resistant, anti graffiti.
|anti-marker, anti-graffiti effect for the manufacture of coating
3 ) Single ended carbinol
Used as a chain terminator and polymer modifier to incorporate a silicone moiety into the polymer structure
Single ended dicarbinol silicone - due to its unique difunctional reactivity, it has the main OH group cured by condensation with isocyanate, epoxy resin, or other resins, providing durability and antifouling property for resins
|Hydroxyl Value (mgKOH/g)
|Single ended monohydroxy
|Single ended dihydroxy
4 ）Double ended tetrahydroxy SL-474X series
Can be integrated in the polymer network by reacting with suitable binders; increases the hydrophobic and oleophobic properties which can signiﬁcantly improve the water- and oil-repelling behavior
