ARMA 952    *    ARMA 901/960    *    ARMA 1500/255    *    ARMA TOP

Product Overview
Seamless, hard, waterproof, chemical-resistant polyurea elastomer providing up to 480% elongation. Its slicker, harder counterpart, ARMA 960, provides exceptional abrasion-resistance.

Product Description
Arma 901 is a state of the art, 100% solids, high performance sprayed plural component polyurea elastomer, and Arma 960 is its harder counterpart. These systems are based on amine-terminated polyether resins, amine chain extenders and isocyanates. Each provides a flexible, extremely tough monolithic membrane with excellent water, chemical, and abrasion resistance.

Polyurea Formulation
Polyurea spray elastomer systems are 100% solids, two-component spray systems which have extremely fast reactivates and cure limits. This technology is similar to the high performance polyurethane systems currently used, except for several key points.

In the polyurea elastomer technology, JEFFAMINE polyoxyalkylene diamines and triamines have replaced the polyols, amino chain extenders are utilized, and catalysts have been eliminated.

This improved chemical formulation allows Arma 901/960 to cure on cold surfaces and provides superior performance under extremely humid conditions.

Features

  • Arma 901/960 are seamless membranes that can be handled and walked on within 30 seconds of the time they are sprayed.
  • Product flexibility is a tremendous advantage of Arma 901. Arma 901/200 stretches to 200% of its original size without any adhesion loss. Arma 901/480 stretches to an amazing 480% of its original size.
  • Arma 960 boasts exceptional abrasion resistance providing a seamless, slick, impact-resistant protective surface.
  • Unlike most polyurethanes and epoxies, Arma 901/960 are hydrophobic and therefore affected very little by damp or cold surfaces. Each can be sprayed directly on moist surfaces, and have been sprayed at -40F/C with minimal effect on tack free time.
  • Due to their almost instantaneous gel time, Arma 901/960 can be built up to any thickness in one application, including vertical and overhead surfaces, which eliminates the need for multi-coat applications.
  • Each coating is 100 % solids. No solvents, no V.O.C.'s.
  • Arma 901/960 have high temperature stability with a working temperature of up to 121C (250F), and intermittent temperatures up to 177C (350F).
  • These products are formulated without the use of catalysts. This increases shelf life of the liquids in the drums as well as enhancing color and light stability in the finished product.
  • Approved: UL94-94 Horizontal Burn Test.
