PureCast Series

High Performance Rubber Parts for Molding, Casting, & Coating

The PureCast products are a line of liquid polyurethane resins that are specifically formulated to create extremely durable, high strength rubber parts. In addition these polymers are also used as abrasion and U.V resistant coatings for synthetic ropes and slings. Available in wide range of Shore hardnesses, from 95A to 55D.

The PureCast Series can be processed at room temperature conditions (72 F). Parts cure to full strength without the need for post curing ovens.

  • Warming the liquid A & B components (100-120F) is recommended to reduce viscosities for casting applications.
  • Maintaining cooler temperatures (72-100F) is recommended for higher viscosities for coating synthetic rope and nylon webbing.

These products feature:

  • High elongation
  • High Tensile strength
  • Excellent tear resistance
  • High hardness without brittleness
  • Chemical Resistance
  • Hydrolysis Resistant (salt and fresh water)

Applications and Uses

  • Durable, high strength rubber parts
    (wheels, bumpers, seals, rollers)
  • Abrasion and U.V. resistant coatings for synthetic ropes and nylon lift slings
  • Casting performance parts
  • Abrasion control pads
  • Helicopter lifting slings and rope eyes

Specific Applications

Semi-Rigid Casting Resins

PureCast 600 is a two-component liquid castable polyurethane elastomer that contains no TDI or MOCA. Purecast 600 is insensitive to typical environmental moisture and exhibits low shrinkage with service temperature range is -50°F to 200°F. PureCast 600 provides the strength and durability of a heat cured urethane in a simple to use RTV system. It provides you with the ability to cast high strength, flexible urethane parts in urethane or silicone molds. PureCast 600 can be colored with RV series pigments. We recommend using black or darker colors to prevent color change or applying a UV resistant topcoat coating. This product is reddish/brown in standard color. Some uses for PureCast 600 include core box liners, metal forming pads, industrial parts and abrasion resistant pads and bumpers.
Product Features:
  • High strength
  • Flexible
  • RTV System
  • Can be colored with RV series pigments
  • U.V. Resistant
  • Longest working life of this series (30-40 min)
Product Uses:
  • Abrasion resistant pads and bumpers

Semi Flexible Rope Coating and Castings

We manufacture products used in coating rope, fabric and netting. These coatings are easy to mix and apply no special application equipment is required, simply mix and apply by gloved hand. Purecast 603 is the most abrasion resistant high build flexible coating we manufacture. It is recommended for coating rope, fabrics and netting where the highest abrasion resistance and durability is required, we offer a selection of 18 color pigments sold separately.

PureCast 603 is a solvent free low odor coating which can be applied in one or more coats as required. PureCast 603 is a US military specification product used in the manufacture of helicopter lifting slings. The cured hardness is 40 Shore D. Purecast is compatible with most synthetic or natural fiber ropes or fabrics. PureCast 603 contains no solvents and is classified as a nonhazardous material for shipping purposes.

Product Features:
  • U.V. Resistant
  • Good for industrial parts
  • Abrasion resistant applications
  • High durability
  • 15-30 min working life
