RP Repair patch Construction:2-layer
First layer: Copolymer hot melting adhesive
Second layer: Radiation-cross-linked, high density polyethylene (unexpanded)
Melting Stick is made of hot melt adhesive same with first layer of RP. In general, RP is available for repairing damage less than 150mm×150mm in size.If damaged area of coating pipeline is larger than 150mm×150mm, Heat shrinkable wraparound sleeve is recommended.Installation is done with gas torches. To repair a damaged area, installers round out,roughen, clean and preheat the area and apply the hot melting.adhesive stick to fill up the holiday. RP, cut to size, is positioned onto the treated area and heated. During heating, the adhesive softens and flows to form atight bond with the backing. The bond strength builds up during cool-down and is fully retained after repairing completion.
FEATURES & BENEFITS
RP provides excellent abrasion resistance, inert to acids and alkalis and solvents, moisture and corrosion resistance. The hot melting adhesive stick is supplied as rods for sealing or repairing smaller damage hole or crack (up to 10mm×10mm),which provides excellent adhesion(to PE, FBE and steel) and moisture resistance.
