Color Sealants in the Field

October 16, 2008

Here's a new idea for contractors and homeowners alike: custom-colored sealants that can be created right on the job site.

Bondaflex(R) Ucolor(R) is a coloring system that enables users to add pigments to both one-part silicone and two-part polyurethane sealants on the job site.  The colorization system virtually eliminates lead times from custom-color orders by allowing users to color in the field -- users simply mix one of the 52 colors in the Ucolor Pak  with their required amount of sealant, making Ucolor ideal for small projects, maintenance jobs and other repairs.

After a three-minute process of mixing the Ucolor Pak with the sealant, users have an exact match for a variety of substrates, providing a uniform, professional appearance. Ucolor can be mixed with Bondaflex(R) Sil 290 FPS-NB and Bondaflex(R) Sil 295 FPS-NB, one-component silicone sealants ideal for use in building, school, parking, plaza, stadium and prison applications.


Sil 290 is a low modulus, neutral-cure silicone sealant that can be used in a variety of construction applications, such as installation and perimeter sealing of windows, doors and skylights; conventional glazing; expansion joints; EIFS systems; precast expansion joints and curtainwalls.

A neutral-cure, high performance silicone weatherseal, Sil 295 is ideal for conventional glazing; perimeter sealing of windows, doors and skylights; expansion joints and precast expansion joints, in addition to unitized curtainwall assembly and field installation.


Bondaflex Technologies, the leading brand of May National Associates Inc., offers high-quality acrylic, polyurethane, hybrid and silicone sealants and adhesives to the commercial construction, fenestration, industrial and transportation markets.


May National Associates Inc., based in Lakewood, N.J., is an innovation-focused organization recognized as the industry leader in the manufacture of acrylic, polyurethane, hybrid and silicone sealants and adhesives, available through Bondaflex Technologies, private label and contract manufacturing.
