KYK MegaEpoxy D501

High Chemical and Mechanical Resistance for Industrial and Hygiene-Critical Areas

KYK MegaEpoxy D501 is a two-component, epoxy resin-based ceramic adhesive and grout material suitable for 3–15 mm joint widths. With its high resistance to acids and alkalis, superior mechanical strength, and suitability for contact with drinking water, it provides a long-lasting and reliable solution, especially for floor and wall applications exposed to heavy-duty conditions.

Application Areas

Adhesive and Grout Applications (Interior/Exterior – Wall & Floor)

• Anti-acid and industrial ceramics
• Granite, glass mosaic, and glass blocks
• Marble and similar covering materials

Suitable Substrates

• Cement-based plaster and screed surfaces
• Concrete surfaces
• Metal surfaces

Special Application Conditions

• Underfloor heating systems (resistant to high temperature variations)
• Areas where chemical resistance and waterproofing performance are critical

Sectoral Application Areas

• Food production facilities (milk, yogurt, cheese production areas, slaughterhouses, integrated meat processing plants)
• Wine and beer factories, filling and bottling facilities
• Industrial kitchens
• Hospitals and laboratories
• Pharmaceutical and cosmetic production areas
• Swimming pools containing salt water or thermal water
• Wastewater treatment plants and wet areas

Product Advantages

As an Adhesive

• High compressive and flexural strength
• Superior resistance against dynamic loads
• Strong bonding performance with no slipping on vertical surfaces
• Solvent-free and environmentally friendly formulation

As a Grout Material

• Antibacterial additives provide resistance against bacteria, mold, fungi, and algae formation
• High chemical resistance and suitability for contact with drinking water
• Low water absorption rate and high abrasion resistance
• Resistant to frost, water, and high temperature variations
• Solvent-free formulation

Surface Preparation

• The surface must be dry, clean, solid, and free from any residues that may prevent adhesion.
• Concrete surfaces must complete a 28-day curing period, and surface moisture must be below 5%.
• Expansion joints must be left according to the project requirements and filled with a suitable polyurethane sealant.
• In wet areas, appropriate primer and waterproofing application must be completed before ceramic installation.
• Surface defects deeper than 2 cm must be repaired with epoxy repair mortar at least 24 hours before application.
• Before grouting, joint gaps must be completely dry and clean.

Mixing Ratio and Preparation

Package Contents:

Component A: 4.650 kg
Component B: 0.350 kg

Component B should be slowly added into Component A.

Mix with a low-speed mixer (approximately 400 rpm) for 3–5 minutes until a homogeneous mixture is obtained.

The entire mixture should be used after preparation.

Application Method

As an Adhesive

The mixed material is poured onto the surface and spread evenly at approximately 2–3 mm thickness. A notched trowel suitable for the size of the covering material should be selected for application.

As a Grout

Apply only into the joint gaps using an epoxy grout float.

The joints must be completely filled, and no residue should remain on the surface.

Cleaning:
Cleaning should be carried out with room-temperature water and a damp sponge.

If a second layer application is required:
It must be completed within a maximum of 5–6 hours after the first application.

Application Conditions

• Ambient temperature: +10°C to +30°C
• Surface temperature must be at least +3°C above the dew point.
• Application should not be performed at temperatures below +10°C or in environments where relative humidity exceeds 75%.
