Product Description
Smooth-Cast™ 61D
The Smooth-Cast™ Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
New Formulations – New Look!
Smooth-Cast™ 61D is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi rigids are now mercury free and phthalate free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ colorants.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.

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
