Polytack MT-1 CLR Spray Adhesive

Description

MT-1 is a NON-HAP proprietary reactive based polymer spray tack adhesive that is designed to bond dry reinforcements and composite matrices, including cores in place prior to introducing resin through various processes like resin infusion, RTM, VARTM, RTM Light or fiberglass pre-forms. MT-1 is uniquely formulated to be highly compatible with most polyester and vinyl ester resins and also can be used with epoxy resins at ~30g/m2 or less with minimal to no effects on laminate bending shear properties. The product is solvent based and after spraying, builds tack within seconds, and will be tack free in approximately 2-3 minutes!

Highlights

- Highly compatible with VE and Polyester resins

- No drop in laminate shear properties

- Tack time 15-20 seconds

- Tack free in 2-3 minutes

- Allows for easy repositioning on mold surfaces

- Mechanically bonds with high initial tack to fiberglass, foam core, and most infusion media

Application

Open tack time is the approximate time after spray application until the product dries tack-free. Product is packaged in easy 12oz aerosol canisters. Product does not settle, and it is not necessary to mix before use. Product must be kept in air-tight containers. Typically, application of less than 15-30 gsm are more than accurate to sufficiently hold reinforcements and independent tests have not shown any measurable loss in physical properties. It is strongly recommended that the user test on their surfaces, gelcoats, or fabric reinforcements to determine suitability then substantiate with physical testing. Contents are Highly Flammable. Use in a well-ventilated area, or use proper Personal Protective Equipment (PPE) with a VOC respirator (recommended). Read Safety Data Sheet before handling or using this product.

Notes

1. The tack time is dependent on temperature.

2. Independent testing has shown little to no appreciable physical properties loss in bending shear testing at higher than normal
applications (< 90 gsm) on VE and Polyester laminates.

3. Using a typical infusion grade Bis A epoxy also has shown no appreciable loss in physical properties at normal application levels <30 gsm. User should always determine suitability of Fibertack spray adhesive for the intended application.
