Acrylic Adhesive WC270

Description

This Acrylic Adhesive WC270 is a two part acrylic cement that dries clear, has a thicker viscosity than the WC105 and is specifically formulated for bonding / fabricating / cementing cast acrylic sheet (Perspex) and components.

WC270 acrylic adhesive can be used across a wide range of industries and applications where the bonding of acrylic to itself and other materials such as wood is required.

Application uses

This acrylic adhesive is ideal for, or known as:

• Rapid bonding of acrylic
• General fabrication work
• Joining items made from cast acrylic (Perspex)
• Acrylic Sheet Adhesive
• Acrylic Weld Cement
• Acrylic glue
• Acrylic adhesive
• Gap fill acrylic
• Acrylic plastic glue
• Acrylic plastic adhesive
• Plastic adhesive
• Plastic sheet adhesive
• Plastic weld cement

WC270 acrylic adhesive cannot be used for structural applications on aircraft.

Components of this adhesive

This two part adhesive comes in two separate bottles ready for mixing, these being:

• 500ml Part A – WC270
• 25ml Part B – WC270

For mixing combine in the ratio of 20:1 Part A:Part B and stir thoroughly but slowly to avoid air bubbles occurring (parts by weight or volume can be used). The cement will not polymerise (harden) properly if different portions of the catalyst (Part B) are used.

Adhesive composition

WC270 is a two part solvent-based adhesive cement. It consists of a mobile monomer/polymer syrup and a liquid catalyst solution.

Hardening

Hardening begins as soon as the catalyst (Part B) is added. Use the mixed cement within 20 minutes, otherwise the bond will be weakened.
After mixing, cover the vessel and leave it until the larger air bubbles have risen to the surface. Remember that the bubbles should be allowed to rise and the job completed in 20 minutes of adding the catalyst. Cementing operations should not be undertaken at temperatures below 15°C as the setting time can be affected. Ideally, the temperature should be 20 +/- 5°C.

Setting begins as soon as the catalyst is added and the cement should be hard within 1½ – 2 hours. After this time, the joint may be handled carefully. Light machining is possible after 4 hours but a better finish and stronger joint will be obtained if left for 24 (twenty-four) hours.

Adhesive benefits

This adhesive has the following benefits:

• Thick Viscosity;
• Slow Curing Speed;
• Allows some repositioning.

Adhesive information

Directions For Use

1. Surfaces to be coated should be clean, dry and free from dust and grease.
2. Mix in the ratio of 20:1 Part A to Part B and stir slowly.
3. Use within 20 minutes of mixing.
4. NB: This is a single use adhesive, once the parts have been mixed together the adhesive will cure and cannot be reused. If you do not require all 500ml for one application then decant to smaller amounts but in the same ratio as before.
5. Setting begins as soon as the catalyst is added and the cement should be hard within 1½ – 2 hours. After this time, the joint may be handled carefully. Light machining is possible after 4 hours but a better finish and stronger joint will be obtained if left for 24 hours.

Precautionary information

1. The gap-filling properties of the cement are limited. Special masking techniques will be needed to keep the cement in place if large gaps are to be filled. In addition, the cement shrinks in volume by 20% as it hardens, so cavities need to be over-filled to allow for this.
2. Part A has a slight purple tinge and Part B is a light straw colour. After prolonged outdoor exposure (years) in warm climates, a slight yellowing of the hardened cement may occur. This will not affect the mechanical properties of the cement.
3. Part B should be stored as above at a temperature between 0 – 5°C. At lower temperatures (- 10°C) the catalyst may crystallise out of solution. If Part B becomes deeply coloured (yellow/orange), the hardening time should be tested by mixing a small amount of both components. Obtain a new bottle of Partt B if the cement sets slowly.
4. Always replace the lid of the container immediately after use to prevent evaporation of the solvent.
5. THIS ADHESIVE IS NOT RECOMMENDED FOR STRUCTURAL APPLICATIONS ON AIRCRAFT.
