Henko R305 Good Weather adhesive is designed for bonding seam tape to artificial grass and for general repair applications. It is suitable for most types of artificial grass and in particular sports pitches.  This system can only be used in dry conditions.  For damp conditions, use Henko R300.

The R305 is a two component adhesive making it well suited for sports pitches or areas where a significant amount of stress on joints may occur.

Ensure that the surfaces to be bonded are smooth, clean and free from dust or other deposits.

Slight moistening of substrates improves the curing rate and gap filling properties. The two component R305 adhesive is best used between +5°C to +30°C. Beware of too much water. We recommend a preliminary compatibility test before bonding of desired substrates.

Mixing instructions:

Mix 'part A' thoroughly using the Henko mixing tool or similar item.

Leave to rest for 2-3 minutes before adding 'part B'.

Ensure that Part A and B are mixed together thoroughly for a recommended time of at least 2 minutes and with the Henko mixing tool.

Leave to stand for approximately 10 minutes before applying to the grass.  This is an important step as it starts the curing process and ensures the adhesive cures correctly.

Use the Henko glue box or a hand trowel to distibute an even amount of adhesive on to the desired area or seam tape.

Pressing the materials during curing is necessary to obtain the highest bond strength and should be done within the 20-30 minute open time. Presure upon joints is always advised to obtain the highest bond strength.

Cured adhesive has to be removed mechanically.

Always test R305 to determine suitability for your particular application prior to use in production.

Handling and Storage

Henko R305 should be stored in a cool, dry place, at a temperature range of between 5°C and 25°C. In these conditions it has a storage life of at least 9 months.

Do not allow freezing of the adhesive under any circumstances.
