Low Viscosity Mercaptan Curing Agent
Low-viscosity thiol curing agents are a special type of chemical typically used to react with thiol groups (sulfur-containing organic compounds) to form strong polymers or composites. This type of curing agent is known for its relatively low viscosity. When coated or impregnated onto the surface, this product can better penetrate into tiny pores and irregular surfaces, improving the adhesion between the cured product and the substrate. Low viscosity mercaptan curing agents are widely used in sealing, adhesives, coatings, composites, electronic packaging, automotive, construction and industrial applications.
In UV curing ink applications, UV offset printing, gravure, roller coating and other low film thickness, low energy, fast printing process applications can increase the curing rate, and the coating surface is dry and non-adhesive. Improve anti-yellowing properties and enhance adhesion to metal, glass, and polymer materials.
