Composites/Thermosets

Chemical anchors relate to steel studs, bolts and anchorages which are bonded into a substrate, using a resin based adhesive system. Ideally suited for high load applications, in virtually all cases the resulting bond is stronger than the base material itself.

Car repair / putties are materials that typically require BPO (sometimes MEKP) to harden. The filler itself is a mixture of fiberglass, (polyester) resin and talc. The resin allows adhesion and the talc makes the material flow smoothly

Polyester road-marking paints for roads and highways compositions consisting of a polyester resin and a catalyst (BPO), applied with specialized striping equipment. For enhanced visibility, reflective glass beads can be dropped into the paint.

Polymer flooring is a production method where a mix of resin with fillers are poured into a mold. Generally a mix is made of 10-25% resin and the rest are fillers such as sand or stones and pigments in order to get the right strength and aspect.

Buttons

When making a polyester button a variety of chemical dyes are added to the polyester to make different colors. The button making process requires a chemical catalyst (for instance MEKP) that hardens the polyester. UI offers a comprehensive product range for the production of buttons, featuring numerous phtalate-free MEKP’s.

Gelcoats

Gelcoat is a material used to provide a high-quality finish on the visible surface of a fiber-reinforced composite. Gelcoats are cured to form crosslinked polymers and are subsequently backed with mixtures of polyester resin and fiberglass. UI is a leading producer of high quality MEKP’s specifically suitable for gelcoats.

Hand Lay Up

Hand lay-up is a simple method whereby glass or other reinforcing mat or woven fabric or roving is positioned manually in the open mold, and resin is poured, brushed, or sprayed over and into the glass plies. UI offers a comprehensive product-range for hand lay-up applications, featuring numerous MEKP’s, AAP’s and blends.

Spray Up

For larger production runs the spray up method is used. In the spray up process the resin and the fiber are spayed onto the mold. Then the laminate is rolled in order to remove air. UI offers a comprehensive product-range for spray-up applications, featuring numerous MEKP’s, AAP’s and blends.

Centrifugal casting is a process for pipe production: the pipe wall is built up from the outside inwards in a rotating mold. Once all the materials have been fed into the mold, the speed of rotation is increased. Centrifugal forces press them against the mold wall. UI offers a comprehensive product-range for centrifugal casting, featuring numerous MEKP’s, AAP’s and blends.

Filament winding is the process of winding resin impregnated glass or advanced fiber around a rotating mandrel, to create a composite structure. The process is to produce large diameter tanks, pipes and many other products. UI offers a comprehensive product-range for filament winding, featuring numerous MEKP’s, AAP’s and blends.
