Securely bonds PVC: developed specifically for bonding PVC

PVC material has many benefits for the construction of marine products; it is lightweight, flexible and durable. However, most adhesives will cause PVC to leach plasticisers, resulting in bond failure.

Apollo Marine (A3701 A/B) ensures a secure bond because it is resistant to plasticisers and has been developed specifically for adhering PVC.

Withstands extreme environmental conditions: heat, chemical and water-resistant

PVC inflatable products are subject to wear and tear, especially boats and life-saving equipment. These products are constantly being dragged in and out of salt water and left to dry in intense temperatures. Apollo Marine (A3701 A/B) is able to withstand such extreme conditions. It has a temperature resistance of -30°C – 120°C and is resistant to both sea water and chemicals.

Extremely versatile: multipurpose adhesive, with several uses

Apollo Marine (A3701 A/B) is a two-component multipurpose adhesive that bonds plasticised and unplasticised PVC, as well as nylon fabric, polyurethane fabric and foam. The versatility of Apollo (A3701 A/B) reduces the number of additional adhesives you need to store onsite. Apollo Marine (A3701 A/B) is also suitable for use as a one-component product for temporary repairs, which is highly convenient if a repair needs to be dealt with quickly and effectively.

Suitable for professional and non-professional use: toluene-free adhesive

It is illegal to sell adhesives that contain toluene to the general public because of the risks it may pose to human health. Apollo Marine (A3701 A/B) is a toluene-free adhesive, which means you can sell it to both professional and non-professional customers. This gives you a larger potential customer base, especially if you wish to sell Apollo Marine (A3701 A/B) to customers who require an easy-to-use repair product.

Minimises cost and task-time: simple to apply and develops a ‘contact type’ bond

Apollo Marine (A3701 A/B) eliminates the need for you to invest in expensive application equipment because it is easily and quickly applied with a brush or roller. It also forms a ‘contact type’ bond after substrates have been pressed together. This gives excellent handling strength, which allows you to move on to the next stage in the process quickly.

  1. Ensure surfaces to be bonded are clean and free from grease and other contaminants. We recommend that you abrade substrates with a clean emery cloth or wipe with Solvent 6.
  2. Mix components A (adhesive) & B (curing agent) of Apollo Marine (A3701 A/B) for five minutes (approximately). Ideally, mix in the proportions supplied or by components A & B at a ratio of 100:6 by weight.
  3. Apply an even coat of the mixed adhesive to both surfaces with a brush, roller coater or serrated trowel. Allow the adhesive to dry for 5-15 minutes or until it is dry to touch (knuckles).
    Please note: Applying two thin coats of adhesive is preferable to ensure maximum adhesion. Leave the first coat to dry for approximately 20-30 minutes before applying the final coat. Allow the final coat to dry for 5 to 15 minutes.
  4. Join the surfaces together using as much pressure as possible. This is to prevent air entrapment. Components may be handled within minutes of being bonded.
