Specific Applications

Fire Resistant Rigid Molds

UraGel 751 FR consists of two thin liquids, part (amber) and part B (blue). After mixing, Uragel 751 FR immediately thickens to a buttery non-sag paste, which forms a high strength rigid bond. UraGel 751 FR is especially well suited for bonding cast or pultruded fiberglass parts and surfaces. When fully cured, UraGel 751 FR (Fire Resistant) forms a rigid “fiberglass like” polymer that is easily sanded or machined into final form. UraGel 751 FR can also be used as rigid mother mold back up for flexible molding compounds.

Best Products for Fire Resistant Rigid Molds

Product Features:
  • Forms a high strength rigid bond
  • thixotropic (self-thickening) nature
  • easy application to difficult overhead and vertical surfaces
Product Uses:
  • Bonding cast or pultruded fiberglass parts and surfaces
  • Maximum water-weight adhesion when applied to concrete, metal, wood, asphalt or masonry

Spray On Rigid Mold Making & Casting

UraGel 760™ is a rigid (75 shore D) Spray-on mother mold making material or low odor fiberglass replacement product. UraGel 760™ is also used for manufacturing in-mold hard parts, reproduction ancient amour and decorative masks. Use this product any time you need to make hard durable parts from a large open-faced mold.

UraGel 760™ is formulated for spraying hard mother back-up molds or hard plastic parts. It can be sprayed into rubber molds 1/2-inch thick in a single application. When fully cured UraGel 760™ forms a rigid “fiberglass like” polymer which is easily sanded or machined and painted to final form. UraGel 760™ is recommended as a rigid Mother Mold back up for flexible Insta-Gel Spray molds. Polyester fabrics and chopped fibers can be used with these materials to enhance strength and durability. UraGel 760’s thick gel consistency makes it easier to work with than fiberglass, no cloth lay-up required. Very thick sections can be created in a single product application, no flammable fumes or odor.

  • High durability rigid plastic parts
  • Recommended as a rigid mother mold back up for flexible Insta-Gel Spray mold

Brush On Rigid Mold Making & Casting

UraGel 770 is a rigid (75 shore D) brush-on mother mold making material or low odor fiberglass replacement product. UraGel 770 is also used for manufacturing in-mold hard parts, reproduction ancient amour and decorative masks. Use this product any time you need to make hard durable parts from a large open faced mold.

UraGel 770™ is formulated for casting hard mother back-up molds or hard plastic parts. It can be brushed into rubber molds 1/2-inch thick in a single application. When fully cured UraGel 770™ forms a rigid “fiberglass like” polymer which is easily sanded or machined and painted to final form. UraGel 770™ is recommended as a rigid Mother mold back up for flexible Insta-Gel molds. Polyester fabrics and chopped fibers can be used with these materials to enhance strength and durability. UraGel 770’s thick gel consistency makes it easier to work with than fiberglass, no cloth lay-up required. Very thick sections can be created in a single product application, no fumes or odor.

Best Products for Brush On Rigid Mold Making & Casting

Product Features:

High Build Semi-Rigid Mold

UraGel 960 is a unique urethane polymer consisting of two thin liquids. After mixing, UraGel 960 immediately thickens to a buttery non-sag paste consistency, which forms a high build semi-rigid polymer when fully cured. UraGel 960 is easily shaped by sanding or milling and is especially well suited for thick spray applications to expanded polystyrene foam or other plastic or metal substrates. UraGel 960 is specifically formulated for application with simple hand held dual cartridge dispensing gun. The thixotropic (self-thickening) nature of UraGel 960 allows for easy application to difficult overhead and vertical surfaces. UraGel 960 contains no solvents or fumes thereby avoiding fire and worker health hazards in contained work environments.

Splicing / Repairing Industrial Cables

UraGel 1500 is a very soft two component polyurethane polymer specifically formulated for the encapsulation and potting of electrical cables. UraGel 1500 has excellent hydrolytic stability and electrical insulating properties.

UraGel 1500 is especially designed for use in applications for splicing or repairing industrial cables. It is well suited for a wide variety of environments subject to extreme cold, water immersion and mechanical wear and abrasion. Optimum performance can be expected when UraGel 1500 is applied to prepared cables in a dry environment. In most applications no primer is required however Primer 450 or Primer EMC-3 is recommended where adhesion is a problem.
