228 Foam Spray Adhesive for Sofas - Does Not Harden Foam - Non-Toxic
Golden Lion 228 spray adhesive for sofa foam is the top choice of sofa and mattress workshops today - it does not harden foam, contains no harmful Toluene, and saves 60-70% of cost compared with hand-brushed adhesive.
1. Why Do Ordinary Adhesives Harden Foam While 228 Sofa Foam Spray Adhesive Does Not?
Most hand-brushed adhesives on the market today contain Toluene solvent, while 228 sofa foam spray adhesive contains no Toluene at all. Toluene is a chemical that thins the adhesive so it brushes easily, but it also soaks deep into the foam surface. After the adhesive dries, Toluene leaves a chemical residue inside the foam's air cells, causing:
– The foam loses its original elasticity
- The foam gradually becomes hard and brittle after 6-12 months
- Sofas sag, deform and the foam crumbles
This is why many sofa workshops receive customer complaints about sofas sagging early even though the foam itself is still physically fine.
2. How Is 228 Sofa Foam Spray Adhesive Different?
Golden Lion 228 spray adhesive is made from 100% imported raw materials from the USA and Germany and **contains no Toluene or Benzene at all**. Instead, 228 uses a surface-bonding formula - the adhesive only grips the foam surface and does not soak deep inside. As a result:
- The foam keeps its elasticity after many years of use
- Sofas do not sag because of hardened foam
- The product meets European export standards for material safety
3. Why Is 228 Adhesive Safe for Workers?
Toluene and Benzene not only damage foam - they are also direct causes of health harm to workers exposed to them every day:
- Continuous inhalation of Toluene causes headaches, dizziness and nausea
- Long-term exposure affects the liver, kidneys and nervous system
- Benzene is classified by the WHO as a Group 1 carcinogen
228 spray adhesive is **odorless and colorless** - workers who spend all day in enclosed workshops are not affected. This is also why 228 is preferred by sofa workshops exporting to Europe, since those markets strictly control occupational safety and materials.

7. Frequently Asked Questions
**How are 228 and Spro adhesives different?**
228 is specialized for foam, sofas and mattresses - soft, porous materials. Spro is specialized for wood, veneer, laminate and car interiors - hard materials with flat surfaces. If your workshop makes sofas, choose 228. If it makes wooden furniture, choose Spro.
**Does 228 adhesive need anything mixed in?**
No mixing needed; use it directly with a spray machine and air compressor. Machine pressure of 4 kg or higher, spray nozzle 3.0 or larger.
**Can I buy retail?**
Yes, a 3 kg can - 600,000 VND, delivered nationwide. Call 0976.884.341 to order and get advice on mixing ratios (if needed) for each type of material.
The prices above exclude 8% VAT. Prices shown in the store include VAT.
**Can 228 be applied by hand, or only with a spray machine?**
A spray machine is the best option. However, it can also be brushed by hand, just slower and less adhesive-saving than spraying.
According to research by world health organizations, Toluene and Benzene are chemicals that are harmful to health and should be limited in production environments
