The Science of Pure Polyurea

Pure polyurea forms through a rapid reaction between an isocyanate component (Part A) and an amine-terminated resin blend (Part B). This reaction is moisture-insensitive and temperature-tolerant, making polyurea the most versatile polymer coating chemistry available.

The resulting polymer matrix features urea linkages that provide exceptional hydrogen bonding, delivering tensile strength up to 4,500 psi, elongation up to 800%, and Shore D hardness from 20 to 70 depending on formulation.

Unlike polyurethanes, pure polyurea can be applied at sub-zero temperatures and cures in seconds, enabling same-day return to service and unmatched productivity on large-scale projects.

Polyurea Performance Data

SPF Thermal Performance

Spray Polyurethane Foam Systems

Spray polyurethane foam (SPF) is created when two liquid components — isocyanate and polyol resin — mix at high pressure and react exothermically, expanding up to 100 times their liquid volume to fill cavities, seal air gaps, and create a continuous insulation envelope.

Closed-cell SPF creates a rigid, high-density foam with exceptional R-value (up to 7.0 per inch), low water vapor permeability, and structural strength. Open-cell SPF provides a softer, more flexible foam ideal for interior cavity fills and acoustical applications.

Both systems eliminate thermal bridging, dramatically reduce air infiltration, and create energy envelopes that outperform fiberglass batts and blown cellulose by a factor of 5 to 1.

Surface Prep

Blast cleaning, acid etching, or mechanical preparation to achieve SSPC SP-6 or better surface profile for optimal polymer adhesion.

Primer Application

Application of moisture-tolerant epoxy or moisture-curing polyurethane primer to maximize adhesion and protect substrate during the window period.

Polymer Spray

Plural-component spray equipment heats and pumps components at precise ratios, atomizing them to produce a seamless, pinhole-free polymer membrane.

Quality Control

Holiday testing, DFT measurement, adhesion pull-off testing, and surface hardness checks ensure the polymer system meets all specification requirements.
