Product Description

Ecoflex™ 5

Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage.  Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.

Smooth-Cast® ONYX™ FAST

Smooth-Cast® ONYX™ is a mercury-free urethane resin that cures at room temperature to a deep black, solid plastic. ONYX™ resins offer the convenience of a 1A:1B by volume mix ratio and have very low viscosities, so they are easy to mix and pour. ONYX™ resins have an ultimate Shore hardness of 80D and offer higher physical properties and higher heat resistance vs. other general purpose resins.ONYX™ FAST resin has a pot life of 2.5 minutes and a cure time of 10-15 minutes. ONYX™ FAST is a good choice for creating fast cold cast bronze, brass, copper, nickel/silver, etc. effects.

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
