Anchorfix capsules are synthetic resin capsules designed for stud fixing that consist of a sealed glass capsule containing a two-part resin and aggregate filler. They provide strong and durable anchoring solutions in various materials and are easy to install, offering advantages over traditional mechanical anchors, such as preventing corrosion and avoiding stress on the substrate. The document includes guidelines for installation, static design loads, and recommendations for use in dynamic loading conditions.

SYNTHETIC RESIN CAPSULES FOR STUD FIXING

3. Anchorfix Capsules
• The ANCHORFIX CAPSULE fixings consist of :
• The specially sealed glass capsule containing the two part synthetic
resin and aggregate filler. The capsule is so designed that the catalyst is
separated in a glass phial within the outer glass tube. There is no
migration between the catalyst and resin thus ensuring a long storage
life for the capsule.
• A length of studding with nut and washer.

4. Strength of Anchorfix Capsules
The ultimate strengths of ANCHORFIX CAPSULE fixings are dependent
upon a number of factors, including the strength of the studding, strength of
the substrate into which the fixing is inserted and the use of the right size
drill for the fixing installed. Pull-out tests have been carried out in triplicate
with fixings correctly installed in 50N/mm² concrete using standard EN1A
studding; the results are given in Table 1.

5. Uses
Where it is necessary to obtain a quick high strength fixing into concrete,
brick, masonry, block-work, rock or other material of sufficient strength to
take the load required of the fixing. ANCHORFIX CAPSULE can be fixed
into horizontal and vertical surfaces, or overhead.

7. It is important to note that results in Table 1 purely give the failure loads of
the mild steel studding and should not be used as safe working loads.
When properly installed into good sound concrete (40N/mm²), the
ANCHORFIX CAPSULE fixings will normally be stronger than the safe
working limits of our standard steel studding. Table II below should serve as
a guide for maximum static design loads for ANCHORFIX CAPSULE
fixings. If ANCHORFIX CAPSULE fixings are to be used in applications
where they are to be subjected to dynamic loading please consult our
Technical Department.

9. Advantages
 ANCHORFIX CAPSULE are quick and easy to fix.
 They are anchored by a chemical bonding action which becomes an integral part of the material into which the
fixing is bedded.
 This ensures that vibratory loads do not affect the bond, neither water nor moisture will be able to enter and
cause corrosion.
 No expansion force or splitting action occurs to the bedding material.
 In light weight materials the ANCHORFIX CAPSULE synthetic resin enters the pores and cavities, so forming
an even stronger fixing.
 Up to now, heavy duty fixings have been made with expansion-type mechanical anchors. In many instances
these have proved satisfactory.
 However, by their very nature, mechanical anchors have to stress the surrounding material in order to function.
This can and often does result in :
i. Fracture in brick, masonry or concrete if the fixing is placed near to an edge.
ii. Fixing working loose or slipping under vibratory conditions or differential loading.
iii. Inability to tighten the fixing fully because of fear of over stressing the bedding material.
iv. Penetration of water into the anchor leading to corrosion.

10. Fixings into Light Weight Materials :
When fixing into lightweight or low strength substrates the Strength of the
substrate is the limiting factor. For recommendations please consult our
Technical Department.
Time to achieve full strength with ANCHORFIX CAPSULE fixings :
The time to achieve full strength is dependent upon temperature. Ensure at
30ºC - 15 min. Table III gives an indication of the minimum time that should
elapse before a load is applied to the fixing. Where loads approaching the
suggested maximum design strength of the fixings given in Table II are to
be applied these times should be extended by at least30%.
