XTEND 800 Semi-Permanent Release
Testing Procedures

XTEND 800 is a reactive resin formulated to crosslink and cure on the mold surface, offering superior durability and extended release performance. It is a one component mold release which requires no primer. To assure maximum adhesion to the mold surface, please follow the application instructions carefully.

Mold Preparation

Seasoned Fiberglass Molds or Metal Molds

> Thoroughly clean molds using one, or more, of the following in succession:

CW-200HS Stripper to remove semi-permanent coatings.

CW-80 To maintain and prep mold surfaces already coated with a semi-permanent coating where stripping is not desired (i.e. to remove excess application of XTEND 800, molding residue or shop dirt before touch up, or to prep molds already coated with a semi-permanent release).

CW-9NC Stripper to remove waxes, polymers and polymerized wax-styrene combinations.

> Apply cleaner or strippers more than once if necessary. Always use a 100% cotton cloth or a stiff natural bristle brush (Rugged Charlie Brush).

> Test mold cleanliness with masking tape. If tape adheres very well, the mold is clean.

Compounded FRP Molds

> Wash mold well with water to remove compounding residue dust and dry with a soft cotton cloth.

> Wipe mold with a wet coat of CW-80. Allow to dry.

New/Green FRP Molds

> New and green molds can vary in their release characteristics. Many manufacturers assist mold break-in and release by using PVA. AXEL's S-19 Sealer, applied before XTEND 800, may also be useful for breaking-in new molds.

Steel, Aluminum and Plated Tools

> Although optional, aluminum and plated tools may benefit from an application of AXEL's S-19 sealer before application of XTEND 800.

Application

> Saturate a clean 100% cotton cloth with release. Cloth should be wet but not dripping.

> Working in small areas wipe on a smooth wet film. Do not over apply. Wait 20-30 seconds and then lightly wipe off excess with a clean cotton cloth. Do not rub.

> Continue application until the entire surface has been coated. Overlap slightly.

> Apply 3-6 coats of release allowing approximately 15 minutes between each coat for drying.

Cure

> Allow the release to cure for a minimum of 15-20 minutes at room temperature (70°F/21°C) before molding.

Break-In

> Apply one coat of release after the first and third releases. This will extend productivity. If the part is pulling easily, continue molding.

Maintenance / Touch-Up

> Wipe on touch up coats of XTEND 800 as needed.

> If necessary, use CW-80 to remove shop dust or molding residue.

> Light applications of CW-80 can also be used to remove excess application of XTEND 800.

Removal

> In the event that molds need to be repaired or re-worked, CW-200HS Stripper may be used to remove XTEND 800.
