Operation Guide for PUR Hot Melt Adhesive Wood-bonding Flat Lamination
● Preheat Equipment & Clean Glue Path
Set the adhesive melter temperature to 110–130℃ and preheat for 30–40 minutes until the adhesive is fully melted. Clean the glue gun and pipeline to avoid blockage, ensuring smooth glue output for stable application.
● Adjust Glue Application Parameters
Set the glue output to 8–12g/m according to substrate thickness, and keep the glue gun 5–8mm away from the substrate surface. Move the gun evenly to form a continuous and uniform glue line without overflow or gaps.
● Substrate Lamination & Pressing
Align the decorative material with the wood substrate immediately after gluing, then press with 0.8–1.2MPa pressure for 3–5 minutes. Ensure no air bubbles between layers to avoid affecting bonding firmness.
● Post-bonding Curing Treatment
Place the bonded panels in a ventilated environment (20–25℃, 50–60% humidity) for 24–48 hours of full curing. Avoid moving or processing the panels during curing to ensure optimal bonding strength.
Q1: What substrates is this PUR hot melt adhesive suitable for profile wrapping?
A1: It is suitable for solid wood, MDF, PVC, aluminum alloy and composite boards. No special pretreatment is needed for these substrates, and it maintains stable and strong adhesion in normal profile wrapping construction.
Q2: What are the recommended storage conditions for this adhesive?
A2: Store it in a sealed state in a cool and dry place at 5-25℃, away from direct sunlight and high temperature. The unopened shelf life is 6 months, and the opened adhesive should be used up as soon as possible to avoid curing.
Q3: What is the optimal construction temperature for this profile wrapping adhesive?
A3: The recommended construction environment temperature is 18-28℃, and the glue tank heating temperature is 120-140℃ (per equipment requirements). Stable temperature ensures good fluidity and uniform coating, avoiding poor bonding due to large temperature differences.
Q4: How to handle the slight delamination of individual bonded parts after profile wrapping?
A4: First clean impurities on the bonding surface, reapply the adhesive with uniform dosage, then press and cure for 1-2 hours. Ensure a dust-free construction environment, and the bonded part will restore stable performance after treatment.
Q5: Can this adhesive match different profile wrapping equipment on the market?
A5: It is highly adaptable to mainstream coating and wrapping equipment. It maintains stable fluidity and coating effect at the standard production speed of 10-14m/min, no need to modify the equipment for adaptation.
