D4 Waterproof Wood Adhesive

Description

Name: D4 Waterproof Wood Adhesive

A waterproof D4 grade wood adhesive with none of the safety issues associated with conventional isocyanate containing (polyurethane) D4 grades.

Features: Excellent water resistance, suitable for water immersion. – Fast setting. – Short press time; It is possible to process wood species like pine or spruce with pressing times of minimum 12 minutes. – Improved adhesion on difficult wood species (e.g. oak, larch). – Low timber staining characteristics; no discolouration of the glue line due to the influence of process heat (e.g. HF-press). – Improved heat and water resistance when using high process temperatures (e.g. 70°C). – Suitable for hard and soft woods. – For interior and exterior jobs.

Application: This is a universal system and is applicable for furniture production, parquet flooring, window frames, window scantling, door manufacturing and solid wood bonding. As a general woodworking/ joinery adhesive. General assembly line work. Radio Frequency/ HF cure systems, wood on wood laminating, and household DIY use. Rapid bond strength development. Suitable for hard and soft woods, decorative laminates, chipboard, blockwood and other engineered timber panels. Can be used in applications where joints may be subjected to short term water contact or exposure to high humidity i.e. kitchen work surfaces, window frames, doors and stairs, but not permanent immersion in water.

Instructions: Preparation: Surfaces to be bonded must be clean, dry and free from dust, grease or contaminants that may hinder adhesion. Mis-machined parts may require longer setting times and could produce a weaker bond. Note: drying time is extended at low temperatures and high humidity.
Application: Apply this adhesive thinly and evenly to one side or, if a high degree of water resistance is required, to both sides, using a spreading machine, glue roller, serrated trowel, glue brush and another suitable device. Do not over apply as this will slow down cure. Clamp surfaces together until adhesive dries. (off in <1 hour: full strength 8 hours). Support until fully cured (8 hours at +20°C). Ensure product is fully dried before water exposure (approx. 1 week). When fitting dowels, the adhesive should be applied to the holes. Best results will be achieved when room, material and adhesive temperature is between +18 to +20oC.
Minimum Pressing Times:
– Assembly gluing: 8 to 15 min.
– Short cycle press at +70°C: approx. 60 sec.
– Boards and block gluing: 15 to 30 min.
– Window scantlings, depending on type of wood:
▪ Softwood (eg. spruce): from 15 min.
▪ Hardwood (eg. oak, beech): approx. 2 hours.
Cleaning: Clean any excess or tools after use with warm soapy water.

Limitations: ▪ Ensure wood doesn’t contain excessive moisture (<10%) ▪ Not suitable for load bearing applications. ▪ Do not use at temperatures below +10°C. ▪ Clean excess adhesive off glue line after clamping before adhesive dries with a damp cloth. ▪ Before staining any wood sand off any excess adhesive.▪ Ensure sufficient clamping pressure, especially important with radio frequency bonding.▪ Use on Laminates: Only suitable for bonding small porous laminate strips. Do not use on nonporous or large areas of laminate. Use CONTACT ADHESIVE or CONTACT ADHJESIVE SF.
▪ Because of the varied nature of wood components, e.g. area of growth, type of pre-treatment etc, unpredictable discolouration may occur on different types of wood such as cherry, beech and others. In certain oaks, iron and tannin can also give this effect. We recommend you test compatibility before carrying out large scale manufacture. Ensure adhesive has fully dried before water exposure (approx. 1 week).
