New adjustable composite positioning system introduced

22 May 2012

3M has introduced the Adjustable Composite Positioning System (ACPS) 11095, an easy-to-use positioning spray designed for pre-infusion resin bond dry reinforcements and composite matrices. The company claims that the unique properties of the ACPS 11095 enable it to integrate into the part during resin infusion, eliminating read-through and transition layers in the part post-cure.

The ACPS 11095 has been uniquely formulated by the company to be compatible with most resin systems, including polyester, vinyl ester and epoxy resins. Thus, it goes down easily on both flat and curved mold designs, and after spraying, the product builds tack within seconds and is tack-free in two to three minutes. Designed with ease-of-use in mind, the product features a distinctive color-change system that gives it a blue color when first sprayed, then fades to clear as it cures. With this feature, the company further boasts, users can easily see the amount of coverage they have achieved and serves as a visual indication of the curing cycle. The 3M ACPS 11095 is also not affected by ambient temperature and/or humidity allowing it to be used in a variety of manufacturing conditions.

Additional user-friendly features of 3M ACPS 11095 include the following:

 • It allows substrates to be easily repositioned without leaving fibers behind simply by peeling back an individual layer and reapplying;
 • If the coating dries before the laying up of materials, an additional coating can be applied at a lower rate, which reactivates the previously applied coating;
 • The product also enables manufacturers to use less than competitive brands.
3M ACPS 11095 also has the ability to hold most types of reinforcement and maintain the position of reinforcement for days without sagging. With typical usage, the company again explains, users will see little to no change in laminate shear properties. Available in aerosol cans as well as five-gallon and 55-gallon containers compatible with most traditional spray equipment, the product is also easy to clean up with most solvents. Finally, 3M ACPS 11095 is approved by Lloyd's Register and DNV.
