Staal Plast Polystyrene Glue, 300 ml

HIPS Tray Assembly and Repair Adhesive, 300ml

Gluing a hydroponic tray with a mismatched adhesive leaves a seam that's only as strong as the bond between two different plastics, which is a common point of failure under the weight of a full reservoir. Staal Plast Polystyrene Glue is formulated from the same High Impact Polystyrene (HIPS) material used in Active Aqua 2.0 INFINITY and IGE Grow Trays, so it fuses to the tray itself rather than just sitting on top of it.

Each 300ml container covers roughly 19 feet of tray seams and cures in 48 to 72 hours at 68 degrees Fahrenheit, with lower temperatures extending that cure time. This listing is sold by the case of 8 only.

Key Features & Benefits

• Exact HIPS Material Match — fuses with Active Aqua 2.0 INFINITY and IGE tray material for a bonded, not just glued, seam.
• Covers About 19 Feet Per Container — gives efficient coverage for standard tray seam repairs and assembly runs.
• Permanent, Durable Seal — resists leaks and weak points once fully cured.
• Case-of-8 Packaging — sized for shops repairing or assembling multiple trays at once.

Who Should Use Staal Plast Polystyrene Glue

This glue fits growers and shops assembling or repairing Active Aqua 2.0 INFINITY or IGE hydroponic trays who want a permanent, leak-resistant HIPS bond rather than a generic adhesive that only sits on the surface.

Frequently Asked Questions

What trays is this glue compatible with?

Active Aqua 2.0 INFINITY Trays and IGE Grow Trays, both of which share the same HIPS base material as this glue. That shared material is what lets the glue fuse to the tray instead of just coating the surface.

How long does it take to cure?

48 to 72 hours at 68 degrees Fahrenheit (20 degrees Celsius). Lower ambient temperatures will extend that cure time, so plan repairs around a warm, stable workspace.

How much coverage does one container provide?

Approximately 19 feet of tray seams per 300ml container, which is enough for most single-tray assembly or repair jobs. A shop repairing several trays should plan on more than one container.

What safety gear should I use when applying this glue?

Breathing protection, goggles, and gloves are recommended while applying and curing the adhesive. Working in a ventilated space also helps during the longer cure window.

Can I buy a single container of this glue?

No, this listing is sold by the case of 8 only, sized for shops handling multiple trays or repair jobs. That case quantity keeps a shop stocked across several repair or assembly runs.
