Akemi Platinum 5.0 P+ — Premium Epoxyacrylate Stone Adhesive
AKEMI® PLATINUM P+ is a premium two-component adhesive based on unsaturated epoxyacrylate resins, available in both flowing and knife-grade consistencies. The Platinum 5.0 generation is engineered for even lower color, better clarity and stronger, faster bonds — making it ideal for color-matching to the whitest stone, quartz and large-format porcelain / Techno Ceramic (Dekton®, Lapitec®, Neolith®, Laminam®). It hardens fast with excellent surface drying, polishes beautifully, and — when properly applied and hardened — is classified as harmless to health for stone and ceramic bonds that contact food.
- Very light, transparent color — excellent color matching even on the whitest surfaces
- Two consistencies — flowing for filling/laminating, knife-grade for vertical joints
- Fast hardening & excellent surface drying — and excellently polishable
- Strong adhesion — on natural stone, quartz and Techno Ceramic, even at higher temperatures
- Resistant to water, petrol & mineral oils — with improved protection against yellowing

| Resistance | Resistant to water, petrol and mineral oils |
| Food Contact | When properly applied and hardened, classified as harmless to health for stone/ceramic bonds contacting food |
| Tool Cleaner | AKEMI® Nitro Thinner (uncured adhesive) |
- Wide field of application thanks to flowing and knife-grade consistencies
- Very light, transparent color for excellent color matching, even to the whitest surfaces
- Fast hardening with excellent surface drying, and excellently polishable
- Improved adhesion and bonding strength — also on Techno Ceramic (large-format porcelain)
- Very good adhesion on natural stone, including at higher temperatures
- Improved protection against yellowing; resistant to water, petrol and mineral oils
- When properly applied and hardened, generally recognized as not injurious to health
Mainly used in stone processing for:
- Bonding natural stone, quartz and ceramics
- Bonding large-size Techno Ceramic — Dekton®, Lapitec®, Neolith®, Laminam®, Kerlite®, Maxfine
- Reinforcing (laminating) natural stone slabs with glass-fiber products
- Forming rock substitutes with crushed rock and sand
Note: only moderate adhesion on fresh, alkaline building materials (e.g. concrete, concrete bricks); bonds frequently exposed to humidity and frost have non-durable resistance.
- The surface to be bonded must be clean, completely dry and roughened.
- If desired, tint with AKEMI® Polyester Colouring Pastes / Concentrates up to max. 5%. Knife-grade can be thinned in any ratio with the flowing grade.
- Add 1 to 3 g of white hardener paste per 100 g of adhesive (4–5 cm of paste from the screw tube ≈ 1 g).
- Mix both components thoroughly. The mixture stays workable for about 5–15 minutes at 68°F (20°C), depending on product and hardener dose.
- After about 15–40 minutes the parts can be further processed (grinding, milling, drilling). Hardening is accelerated by heat and delayed by cold.
- Clean tools with AKEMI® Nitro Thinner before the adhesive cures.
- Keep the hardener dose in range: more than 4% reduces adhesion and worsens surface drying; more than 3% causes marked yellowing; less than 1% (and temperatures below 41°F / 5°C) greatly delays hardening.
- Do not use adhesive that has already thickened or begun to gel.
- Keep bonding layers as thin as possible (< 1 mm) — shrinkage is approximately 5–8% due to the high reactivity and heat of curing.
- Once hardened, the adhesive can only be removed mechanically or by high heat (above 392°F / 200°C), not with solvents.
- Industrial chemical product — use only in well-ventilated areas and wear chemical-resistant gloves and eye protection. Always consult the AKEMI Safety Data Sheet (SDS) before use.
