Axel Mold Wiz is a liquid external release agent that dries at room temperature forming a monomolecular film which adheres by absorption to the mold surface and has no affinity for the molded resin or rubber. This selective adhesion prevents the film from being easily abraded by the demolded part.

Numerous demoldings per application of release agent can be expected without any necessity for washing the parts. The release will not interfere with secondary finishing operations such as decorating, bonding, or painting
Uses: Polyester, Epoxy, Acrylic, Methyl methacrylate, Phenolic, Rubber. Winding, Hot press molding & Preforms for all molding surfaces.

SPECIFIC GRAVITY: 0.990 @ 25ºC

VISCOSITY: < 50 cps @ 25°C

pH: 8.7 – 10.7

Application Instructions:

Clean mold with CleanWiz. Apply mold release with a clean cotton cloth wiping in two directions, using a circular motion. Allow to dry for five minutes. Spray a thin coat (fine mist to dry film) and allow to dry completely with no moisture residue. Accelerate drying time by blowing hot air or by using heat lamps. Repeat whenever mold has been cleaned with CleanWiz or as required to give mold release properties.

MoldWiz® WB-2700 is a water-based release that is ideally suited to the rigorous molding conditions of the filament winding process. The release product is a silicone free emulsion of fatty acids, polyolefins, and surfactants in a water vehicle.

The product contains no hazardous materials making it friendly to both the user and the environment. MoldWiz® WB-2700, is a 10% active release product that can be easily diluted if desired.

CASE STUDY:

THE PROBLEM: A manufacturer of large diameter epoxy piping used for chemical conveyance, has historically relied on a solvent-based mold release to release 35’ (10.6 meter) pipe sections from non-tapered steel mandrels. Although the solvent-based release provided reasonable release, constant reapplication of mold release resulted in mandrels with crusty deposits of release and resin that were difficult and time consuming to remove.

In addition, there were growing HMIS concerns regarding volatile solvent emissions, and storage of flammable material.

THE TRIAL

MoldWiz® WB-2700 was introduced in a wet winding process employing epoxy resin. The polished steel mandrels were initially prepared by applying release with a handpump spray bottle and then simply wiped with a cloth to evenly distribute the release over the mandrel surface. The first pipe section released cleanly, pulling easily from the test mandrel. Following the trial, all of the production mandrels were converted to MoldWiz® WB-2700. After the initial release preparation, MoldWiz® WB-2700 is used in dilute form (50% water/50% MoldWiz®WB2700), with one coat applied prior to each wrapping cycle.

THE SOLUTION

The customer credits MoldWiz® WB-2700 with providing good release and eliminating the buildup problems that had been common with the solvent-based mold release.

Workers are pleased with the elimination of a solvent-based release from their workplace and the company’s health and safety objectives have been met.

Tooling Systems From Scott Bader
Scott Bader has a new range of high performance matched tooling systems that are ideal for the following sectors

• Land transport
• Marine
• Building
• Industrial
• Applications that require a superior gelcoat surface finish

Crystic Gelcoat 15PA (B) and (S)

Crystic VE679PA Skincoat& lightweight Reinforcement Construct the mold with either Crystic RTR 4000PA or Crystic 474 PA & your choice of reinforcement

CrysticGelcoat 15PA (B) & (S) CrysticGelcoat 15PA, both brush and spray,
represent the highest quality in tooling gelcoat manufacture.
A superior vinylester resin technology offers a premium finish with exceptional resistance to chemical attack and extremely long life cycles and multiple pulls.

“Very easy to spray with, covers nicely and no sagging. The degassing is perfect and no pinholes were found even after sanding the surface of the gel coat. But where it really out performs the competition is in achieving excellent resistance to print-through when vacuum bagging a 2 x 2 twill carbon fabric of 200 gm-2 with epoxy resin.”
