Product Description
PMC™-780 WET
PMC™-780 is a premium performance urethane rubber that offers exceptional strength, durability and abrasion resistance. PMC™-780 DOES NOT CONTAIN MOCA – a known cancer causing agent and hazard. Mixed two parts A to one part B by weight or volume, PMC™-780 urethane pours easily and cures at room temperature with negligible shrinkage to a solid Shore 80A rubber.
EpoxAmite™ 103
EpoxAmite™ 103 is an easy-to-use liquid epoxy system formulated for a wide variety of fabrication applications. EpoxAmite™ 103 includes the EpoxAmite™ 100 Base and the EpoxAmite™ 103 SLOW Hardener. EpoxAmite™ 103 is unfilled, low in viscosity, odorless and cures at room temperature. Cured epoxy displays exceptional physical and performance properties. It can be sanded, shaped, machined, drilled, tapped and painted.
EpoxAmite™ 103 can be used with reinforcements such as S-Glass, E-Glass, Kevlar and Carbon fibers for lay-up applications or composite parts. EpoxAmite™ 101 can also be mixed with fillers such as fumed silica for gel coat applications. Urefil™ 3, Urefil™ 7 and other fillers can be added for fairing, filleting or bonding applications.
Applications: Wet Lay-Up Lamination, General Bonding & Repair, Clear Coating - Gel Coating, Barrier Coating, Thin-Section Casting, Water Proofing, Patching & Small Laminates
Also available: EpoxAmite™ 101 FAST SET and EpoxAmite™ 102 MEDIUM SET
