SiSiB® PC4100 is a clear, light and heat sensitive liquid with a faintly sweet odour. It is a methacryl-functional silane. It is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes. It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture; functionalize resins via radical initiated processes - copolymerization or grafting and to modify surfaces; improve strength as glass fiber size composite in reinforced polyester composites; enhance initial and wet strength of reinforced polyester resin composites; enhance the wet electrical properties of many mineral-filled and reinforced composites; and improve adhesion and durability of adhesives and coatings.
SiSiB Silicones has more than 20 years’ experience in manufacturing various silicone materials. They have established six factories in China to manufacture organofunctional silanes (silane coupling agents, silane crosslinkers, silane blocking agents), silicone fluids (straight, modified), silicone rubbers (Gum, HTV, RTV and LSR), silicone resins and fumed silica.
SiSiB® silanes are widely used in adhesives and sealants to improve environmental resistance, increase adhesion and other mechanical properties, provide a secondary moisture-activated curing mechanism, filler modification, surface priming, end-capping strategies, water scavenging, formulation stability, adhesion catalysis, etc.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
